Pin fastening



Patented Mar. 31, 1931 UNITED STATES MAKAHIWA x. LUA, or HONOLULU,-rnnmronx or HAWAII PIN FASTENING Application filed January 31, 1930.Serial No. 424,980.

This invention relates to certain new and useful improvements in safetyor looking catches for jewelry, insignia and the like.

An object of the invention contemplates the provision and arrangement ofa locking device of this character designed for engagement with theattaching portion of the form of jewelry or insignia.

An additional obj eot of the invention con- 19 sists in the arrangementof guide portions upon the attaching portions of the jewelry or insigniaby meansof which the locking element can be easily, efiectively andexpeditiously applied.

More specifically stated the locking element is provided with a flexibleform of connection with the article of jewelry or insignia to preventits being lost when not in 1158. With the above and other objects inview,

the invention further consists of the followin novel features anddetails of constructlon, to be hereinafter more fully described,illustrated in the accompanying drawing and pointed out in the appendedclaims.

In the drawing 2- Figure 1 is a fragmentary elevation of theconventional four-in-hand tie or cravat showing a stick-pin applied inthe knot'therefor and exhibiting only that part of the stick-pincarrying the form of ornamentation. 7

Figure 2 is a side elevation of the present invention with the lockingelement suspended therefrom.

Figure 3 is a sectional view taken on line 33 of Figure 2.

Figure 4 is a fragmentary longitudinal sectional viewtaken through aportion of the attaching shank of the article of jewelry with thelocking element applied.

Fi re 5 is a horizontal sectional view taken through the attaching shankwith the locking element in use.

Figure 6 is a side elevation of the locking element per se.

Figures 7 and 8 are end elevationsrof the locking element. 7

Referring to the drawing in detail wherein like characters of referencedenote correspondlng parts, the reference character 10 lndlcatesgenerally the attaching shank of an article of jewelry, insignia and thelike which is provided with a pointed or penetrat- .ing extremity 11upon one end thereof. 'The shank being also bent upon itself orotherwlse offset, as at 12, upon its uppermost end .to facilitate themounting and securing of a plate 13 having its exposed face covered ortreated with means of ornamental character.

The above construction is old and usual in stick or tie pin constructionand forms no part of the present application for Letters Patent but ismerely mentioned for purposes of illustration in bringing forward thenovel advantages of the present invention.

The invention primarily resides inthe arrangement'of an ear 14' carriedby and clepending from the offset or shoulder portion 12 upon theuppermost end of the shank 10 and immediately behind the plate 13. Achain orother flexible form of connection, such as indicated at 15, isjoined at its uppermost end with the ear 14 incident to the passing of aconnecting link' 16 through the aperture therein. The shank proper isprovided with longitudinally extending cross sectional v-shaped groovesor recesses 17 upon diametrically opposite sides thereof andhorizontally drilled at intervals thereon ,to provide passageways' 18.These passageways are preferably located at the intersections of theoppositely and obliquely inclined side walls of the grooves or recesses17, in the manner suggested in Figure 5 of the drawing.

The locking element, alluded to in the foregoing, comprises a platemember 19 having a length of felt or packing, such as indicated at 20,upon the under face thereof designed for contacting engagement with theadjacent surface portion of the shank 10 right angularly disposed toeach of the recesses 17 and in parallelism with the passageways 18.Spring elements, such as indicated at 21, carried at intervals upon theunder face of the plate member 19 and curved upon themselves in themanner shown in Figures 2, 5 and 6 of the drawing exert constantdownward tension with the penetrating elements 22 carried upon theopposite ends thereof. These penetrating elements are designed forinsertion within the passageways 18 and for subsequent lockingengagement within the hooked eXtremities 23 of arms 24 disposed atintervals upon the opposite end of the plate member 19 and upon theunder face thereof.

Although I have shown and described my invention as being designed forapplication upon the attaching shanks of stick or scarf pins, it is tobe understood that I do not limit myself to this particular applicationinasmuch as the locking device may be equally and effectually as wellapplied upon the attaching shanks of badges, emblems, and other forms ofinsignia.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is here in reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention, what is claimed is 1. The combination ofa pin having passageways in the attaching shank therefor, said shankbeing recessed longitudinally thereof and extending for appreciabledistances beyond the passageways therein, said recesses being of V-shapein cross section, and of a locking element having arms guided terminallythereof upon the inclined side walls of the recesses toward thepassageways for projection therethrough.

2. The combination of a pin having passageways in the attaching shanktherefor, said shank being recessed longitudinally thereof and extendingfor appreciable distances beyond the passageways therein, said recessesbeing of V-shape in cross section, of a locking element having armsguided terminally thereof upon the inclined side walls of the recessestoward the passageways for projection therethrough, and retainingelements upon the locking element for the projecting extremities of saidarms.

In testimony whereof I aflix my signature.
